Android Question randomaccessfile.RandomAccessFile.ReadInt(RandomAccessFile.java:137)

[Franck Danard]

Hi

I've got this issue this morning day.

at anywheresoftware.b4a.randomaccessfile.RandomAccessFile.ReadInt(RandomAccessFile.java:137)

It worked fine yesterday evening.

    LoadSettings( File.DirInternal, "settings.conf")

    .../...

    Sub LoadSettings( Dir As String, FileName As String)
       If Dir="" Or FileName="" Then
           Msgbox( "Empty Dir or FileName","error")
           Return
       End If
       Dim raf As RandomAccessFile
       raf.Initialize( Dir, FileName, False)
       SettingsMap = raf.ReadEncryptedObject( "123456", raf.CurrentPosition) <---- Crach here.
     
       raf.Close
    End Sub

Any idea?

It's harder to say something if you don't post the full stack of the error

I guess you have not data in your file
Based on this answer: https://stackoverflow.com/questions/20644505/bufferunderflowexception-java

 

[Franck Danard]

i'll check

 

[Franck Danard]

Hmm.
I don't understand anything.

I check if the file exist and i enabled the writing on the file and now i've got an error.

raf.WriteEncryptedObject( SettingsMap, "123456", raf.CurrentPosition)

Give this error!

I wondered if there's no problem with the IDE and the code pushed on the mobile.
Sometimes i change the code, and i've got the same result.
If i close B4A, i uninstall my project and re-open this one, the code seems good or not (but there's some changes anyway).
I've a real doubt about the real changes and app running on my mobile.
Sometimes i feel that's a early version and not the one with the real changes.
Weird anyway.

This is for this reason that's pretty confuse.

java.lang.RuntimeException: Object should first be initialized (Map).

Unistall the project and re-open it doesn't help you. There is not a bug in the IDE. The error is explained: You need to inizialize the map (SettingMap that you are passing in raf.WriteEncryptedObject)

Already done

   SettingsMap.Put( "url", url_ip.Text)
   SaveSettings( File.DirInternal, "settings.conf")

Can you upload an example project to allows me and other to help you? Sorry but without the code i can't help you

I just started a new conversation with attached file including the project
